What an excellent team to deal with! Fair price for a replacement ECU, especially as immediately connected it was fully working! Great service, dispatch … More and delivery times, and price! Hope not having to use your services again but if needed you're first choice!

I took my FRM3 module to ECU connection to be repaired as I was having faults with certain lights on my E91. I was working away for the week so I dropped … More it off on Friday to be collected the following Friday. Justin called me to say that my module didn't appear to have the usual errors and suggested I get me a donor module as mine was likely damaged. As I was away he sorted this for me and transferred the data over. Unfortunately this didn't fix the problem and it was something deeper, so they did more work to find the fault, at no extra cost! I popped down to just collect the module but Justin dropped what he was doing and ensured my car was sorted and everything was as it should be before I left. Top service and I would 100% recommend.

I have a 2003 Mini Cooper S, originally a UK car but now registered in Switzerland. The BCM gave up and I could not switch off the left headlight. The … More local BMW dealer had no idea what to do and refused to work on it. I sent the original BCM plus one I bought on eBay to ECUconnection for cloning. Good communication, rapid turn around and....it works! Many thanks and a strong recommendation from me :-).

I actually can't believe how effective the repair to my Ford Focus MK2 cluster has been, I was trying to delay my review to see if the faults would … More return but everything seems hunky dory. I have a friend that scrapped their car because they didn't know you could get the issue fixed so easily. Another couple of years of life in my old girl now though. Thank you

Great service and recommend this company . Reprogrammed my Megane BCM and donor BCM so now have 2 working units ( one now a spare ) after losing data due … More to flat battery corrupting files . Saved a lot of money not taking to dealer and saved my car car from scrap yard . Communication excellent.

Quick friendly efficient service on my faulty Ford cluster. Completed in 3 hours and all works perfectly. Would use again (hopefully not soon!)(Photo attached … More was the issue on my Kuga - if anyone else has this problem come up on thier dash and the vehicle not start, it may be this!)

My Daughter's 09 Focus showed all the classic faults of a bad instrument cluster. 'Engine Malfunction' warning, 'Speed Limited' … More warning and the needles dropping to zero. Sent the cluster off and it was turned around in 1 day and back within 3 (Thurs-Sat). Works perfectly and has cleared all the issues. Thank you, Thank you !Absolutely brilliant service, would give you 10 out of 5 if I could !

Very very pleased so far with the service despite two replacement ECU not working in my van. I was kept informed from the outset and my replacement ECU's … More were sent quickly (next day).Justin was very helpful - we tried two replacement ECU's and now they are sending a third one to help me out of a tight spot.I'd requested a refund at one point and this happened in full instantly. So I highly recommend JC Cars and ECU Connections. They were also cheaper than some other ECU clone places I found on the internet. They couldn't be more helpful or efficient.Geoff Grove
