I have never experienced such helpful service in my many years of dealing with the auto trade. Never too much trouble to help and it seems like they would rather help fix your car than let you spend money. 5 star service

I was quoted £1400 to repair my Haldex controller by a VW specialist in Basingstoke. I discovered Matt's website and read the reviews...everything everyone says is true. He's both a genius and an incredibly nice, helpful person too. He gave me the confidence to remove my controller, which I sent the same day (Tuesday). Following day Matt rang to explain what he'd found, and that he could fix it. It was back with me Thursday morning, and by lunchtime, the car was fixed. Wow, what amazing service.

Amazing service! My 2004 Audi A3 Haldex ECU had salt crystals inside from water ingress, causing damage to the PCB. After finding the Haldex Repairs website, I gave them a call and I immediately knew I'd found the right man for the job! I sent it off, Matt called the next day to say that he'd repaired and tested it fine and I had it back the day after that, all working fine! Superb all round - highly recommended!

After finding out that my MK5 Golf R32 Haldex Controller was apparently toasted and getting quoted around £1100 to replace I decided to do a bit of googling where I luckily came across this company, after a quick ring the advice and guidance I received was amazing!! I sent the controller late Thursday and received it back on Monday morning, fitted late afternoon and everything’s working as before!! I’d go as far as saying that if he can’t repair it then no one can, extremely pleased with the level of service I received and would highly recommend them!!

What a find! I can't say how glad I was to find Auto Fault Finder. I was looking at a bill of £937 from my local Audi dealer for a new Haldex controller for my Audi A3 Quattro. Sent the faulty unit to them on Tuesday, Matt rang me Wednesday to say it's repaired and got it back Thursday morning in time for me to fit it. Superb service and great delivery at a reasonable price. What more could you ask for.

Absolutely outstanding service. Everything fully explained. First class workmanship. Very prompt and efficient service. Do not send your Haldex module anywhere else for repair. I cannot rate this company highly enough. They fixed the unit in 24 hours, where as another "repairer" took 4 weeks and 4 botched attempts. Genuinely honest guy. Best value for money I've ever spent on electronic control unit repair.

Top lad, genuine person , I deal with a lot of people with my job (selling cars) and it's very rear you come across someone you can trust that you don't know but Mathew fixed my Haldex for my Golf GT TDI 4 motion after another so called repair man tried to fix it after butchering it, Mathew then repaired it to a high standard and put it back together and sent it back to us, we later realised that the original so called fixer left parts of our Haldex off, then off his own back Mathew sent me the missing parts that the original so called fixer left off, bear in mind we're not talking about parts you can find at ecp , really appreciate your knowledge and VERY professional approach you take to dealing with with this vonerable situation we found ourselves in, top lad 100% wound use again , Steve yorkars

My Suzuki Jimny kept stalling when stopping at junctions and fuel economy was really poor. I struggled to find the problem so took it to Auto Fault Finder. In no time their diagnostics team had sussed out the fault and pinpointed a faulty TPS sensor which was promptly replaced. The issue was solved in a thorough and professional manor. I highly recommend the services these guys offer. Thank you!

Generation 2 Haldex

Q1.Which Cars Are Generation 2?

Typically Gen 2 units are fitted to VW audi vehicles between 2003 to 2009 including Golf R32, Passat R35 and 3.2, Audi A3 S3 8P 2003 to 2008, Audi TT Mk2 8J 2006 to 2010 and almost every other VW, Audi, Seat and Skoda vehicle between 2003 and 2010.

Q2.What is the best way to get this fixed?

The easiest way to resolve Gen 2 Haldex faults is to get the ECU removed from the vehicle and send it to us via Royal Mail Special delivery for a same day test and repair service. You cannot drive the car with the ECU removed, and once removed if you shake the ECU you will typically hear the salt inside it.

Q3.What Are Generation 2 Part Numbers?

These generation 2 control units have the following part numbers:-

1K0907554 1K0907554A 1K0907554B 1K0907554C 1K0907554F 1K0907554K 1K0907554L – All original manufacturer fitted units.

1K0525130 1K0525130A 1K0525130B 1K0525130C 1K0525130F 1K0525130L – Units fitted later in the vehicles life as a replacement unit from VW Audi.

All Generation 2 controllers are cross compatable so they can be swapped without any coding or problems, except those fitted to VW Transporter vehicles with the Diff Lock function. They have a slightly different PCB population and software version.

Q4.What Are The Typical Fault Codes?

  • 02248 – Valve for Controlling Clutch Operating Angle (N373) 014 – Defective – Intermittent
  • 00448 – Haldex Clutch Pump (V181) 014 – Defective – Intermittent
  • 02249 – Sensor for Oil Pressure and Oil Temperature (G437) 004 – No signal OR 014 – Defective – Intermittent
  • 00003 – Control module faulty sporadic – 014
  • 01324 – All Wheel Drive Control Module -J492- 013 – Read Fault Memory sporadic
  • 65535 – Internal Control Module Memory Error 00-10 – Intermittent
  • 01324 – Control module for ALL WHEEL DRIVE (J492) 004 – No signal/communication – intermittent.
  • 00003 – Control Module 014 – Defective – Intermittent / Control module faulty sporadic
  • 16347 – Control Module – EEPROM error – 014 – Defective – Intermittent

 

 

Generation 4 Haldex

Q1.Which Cars Are Generation 4?

Typical Generation 4 Haldex systens are often found fitted to the Audi S3 A3 2009 onwards, late model post 2009 VW Golfs including R32, GTti and Golf R, Audi TT including TTRS TTS, Passat 4-Motion R36, VW Transporters and the VW Tiguan along with other VW Audi Seat and Skoda vehicles of this age.
These generation 4 control units have the following part numbers:-

Audi TT, TTS, A3, S3, Seat Altea, Skoda Yeti, Superb, VW Golf 4 Motion R32, GTi, R32
0BR907554 – 0BR907554A – 0BR907554B – 0BR907554C – 0BR598554 – 0BR598554A – 0BR598554B

VW Transporter (note Diff Lock – Not Compatible with other Gen 4 Controllers – Rare)
09N907554A – 09N598554 – 09N598554A

VW Tiguan, Sharan, Seat Alhambra
0AY907554C – 0AY907554D – 0AY907554E – 0AY598554 – 0AY598554A – 0AY598554B – 0AY598554C

Audi Q3, VW Passat All Track
0BS907554 – 0BS907554A – 0BS907554B – 0BS907554C – 0BS598554 – 0BS598554A

Q.2 Is the problem my pump and filter?

Typically after 50k to 70k the filter blocks up on these Gen 4 vehicl

es. You will be told by dealers, garages and parts suppliers that there is no filter on t

hese systems. The photo and diagram above show the filter but VW/Audi claim they are fitted for life, and a non servicable item! You cannot buy one from them as there is no part number etc. As the filter gets clogged the pump motor works over time wearing out the brushes and bearings and overheating the copper winding. Once the motor goes above or below the 7 ohm coil rating it will no longer pump correctly and needs to be replaced. We can supply replacement filters and pumps.

Q3.What is the best way to get this fixed?

The most common fault with these vehicles is caused by a clogged internal oil filter which burns out the motor inside the pump. We stock Generation 4 pumps, oil and filters to offer a same day dispatch. The filter is removed by using the oil pumps pressure to push out the filter cartridge, but if the pump does not work you first have to replace the pump and oil. Once the filter has been replaced you then refill the unit with oil. These ECU’s do also corrode, and unfortunately they give the same fault symptoms for both corrosion and pump failure making unskilled or inexperienced accurate diagnosis difficult. We offer the Mail Order testing and repair service for ECUs/controllers giving you the ability to fix your Gen 4 vehicle effectively.

 

 

Q4.What Are The Typical Fault Codes?

  • 02248 – Valve for Controlling Clutch Operating Angle (N373) – 014 Defective – Intermittent
  • 00448 – Haldex Clutch Pump (V181) – 002 – Lower Limit Exceeded – Intermittent
  • 01155 – Clutch – 003 – Mechanical Failure – Intermittent
  • 00448 – Haldex Clutch Pump (V181) – 011 – Open Circuit – Intermittent
  • 02248 – Valve for Controlling Clutch Operating Angle (N373) – 012 – Electrical Fault in Circuit
  • 01155 – Clutch – 003 – Mechanical Failure – Intermittent
  • 01324 – Control Module for All Wheel Drive (J492) 004 – No Signal/Communication
  • 65535 – Internal Control Module Memory Error 00-10 – Intermittent
  • 16347 – Control Module – EEPROM error – 014 – Defective – Intermittent
  • 00003 – Control Module 014 – Defective – Intermittent / Control module faulty sporadic

 

 

 

ECU Repair Service Frequently Asked Questions

01. Can You Repair Volvo and Ford Unit?

Yes, we have testing facilities for Ford and Volvo unit, please see our page dedicated to Volvo and Ford units.

02. Can I drive the car once the ECU is removed?

It is possible to slowly move the car in and out of a garage, but the vehicle must not be driven over walking pace as oil will leak out of the coupling and there is a risk of losing the slot in valve and sensor. So you must not drive the vehicle once the ECU is removed.

03. How does the mail order service work?

  • You send your ECU to the address at the bottom of the page via Royal Mail Special Delivery (about £7.50).
  • On the day we receive it we will test it, if faulty we will fix it if viable and reseal it.
  • If not faulty or not viable for repair we will rebuild it and seal it back up.
  • We will call you at around 4pm to take payment.
  • We will send it back to you via Royal Mail Special Delivery for next day delivery.

04. Do you stock replacement controllers?

There is more demand for replacement controllers than we have supply. We occasionally have a Gen2 or Gen4 controller available but they are usually sold very quickly. Be cautious buying second hand controllers as the all have some element of corrosion inside. If you wish we can test and reseal your own replacement controller which will seriously extend its life expectancy.

05. How Can I Make Payment?

We accept all Credit and Debit cards over the phone or in person. We can also take bank transfers or Paypal.

06. What is your success rate for repairs?

For Generation 2 and Generation 4 controllers we are getting around a 95% success rate for corrosion repairs. But less than 50% of all Gen 4 units sent in are are actually faulty as the most common cause of the problem is defective pumps and clogged up filters which we stock and can sell via mail order.

07. Can you supply other parts of the system?

We hold a small quantity of Gasket Plates, Concaved Washers, Fixing Screws, Clutch/Couple Opening Oil Control Valves (N373) and Pressure Sensors (G437). Mostly these are used/second hand components but helpful when missing. Please enquire for prices and availability.
