    Absolutely first class service and warranty! Matt repaired my 2004 Audi A3's Haldex controller back in 2018 and it's been perfect for the last 7 years. Unfortunately the traction control light came on at the exact moment between the service and MOT last week. I got in contact with Matt again and he said to send it in and they would repair it free of charge, under their lifetime warranty. True to his word, it was back with my mechanic within 48 hours, with a brand new PCB fitted. Thanks again Matt!

    Mat is awesome and a Haldex master. Thank you for your advice and help. Avoid Audi main dealers for a Haldex service as mine was done 4000 miles ago and this is what it looked like when I removed it

    If I could give more stars I would because these guys are good at what they do I went to so many places. To sort out the ecu problem I had. As everyone else said they won’t be able to repair. These guys on. The other hand the day I gave it the next day I received it next day before I even woke up. Great guys Great service everything they said or done was spot on 10/10 for everything would very very much highly recommend these guys

    Took my Audi S1 to an Audi independent garage. Fault diagnosed as Haldex controller, cost £1000 to replace. Found this company through Google, though I was somewhat sceptical. Paid the money and send off my controller on a Wednesday afternoon. It arrived back in a jiffy bag on the Friday around noon (I did wonder whether I had attached the wrong label and sent it back to myself). Astonishingly quick turnaround. Dropped it off with the Audi specialist who put in back in the car and hey presto, all fixed. Superb !

    INCREDIBLE! If all businesses were run like this, the world would be a much better place! My R32 was having Haldex issues and before sending it into my local VW independent garage, I researched that my issue was likely to be my Haldex Controller. I asked my garage to send my controller to Matthew, who diagnosed it, repaired it and sent it back to my garage the same day they received it! Hey presto, no more issues! That's a tick for great service, a tick for refurbishing a part that a VW main dealer would simply throw in land fill and replace with a new part at over 4 times the cost of refurbishment and a tick for returning the refurbished part back properly sealed, which they aren't when they leave the VW factory. Keep up the good work!

    Car failed it's MOT because of a faulty haldex control unit. Replacement part was on backorder, car was effectively off the road without these guys! Guys repaired the unit and send it back all within a few days! Great service, can't recommend them highly enough.

    Had an issue with water ingress in my gen 5 haldex control unit. Spoke to Auto Fault finders on the phone being recommended to use them by members on a forum and the knowledge they have is amazing and really helpful. Talked me through why they are common issues on my car and how the process they carry out to resolve it. I send mine off on a Wednesday and got it back Friday morning. Amazing service I would recommend them to anyone!

    Outstanding customer service. Sent in my email query and Matthew spent a good hour over the course of a few weeks on the phone to me. I eventually sent in the Haldex on a Monday. It was benched, repaired and sent back out Tuesday PM, then re-fitted to my (now) working LR on Wednesday! Significantly cheaper than a new JLR part. Would give a 6th star if there was one!
