ECUconnection

Graham Parker ★★★★★ a week ago
Sent my Ford Focus dashboard to ECUconnection as was faulty (multiple warning lights, alarms and dials stopping working), … More it was repaired within a couple of days and worked well once refitted.
Throughout the process I was well informed of what was going on and all at a very reasonable price.

I was getting the random warning lights on the instrument cluster of my ford focus, and the car going into reduced acceleration … More mode. The internet diagnosed the problem as cracking solder, and gave a wildly varying range of price for the repair. In the end I went for ECUconnection as they were the cheapest, but most importantly because they put the very helpful video on youtube on how to remove the instrument cluster. You put helpful content for free, you get my custom. Sounds fair. A few working days after posting the cluster, I got it back, and all the warning lights cleared immediately, bar the engine warning, that disappeared after the second restart. I’m very happy with the service.

I had a great experience, 100% recommend. They have been very helpful, promptly responded to every question and updated me … More at every stage. I sent my faulty ECU to them which unfortunately wasn't fixable. They promptly contacted me with a solution. Got my new ECU back after a short time perfectly working and for a reasonable price.

Could not have gone smoother!! Sent my cluster in for repair, got a message next day to say it had been received and would … More be 3 to 5 fay's turn around! Got another message to say it was repaired and being dispatched. Arrived next day put it back in car , good as new. Cannot recommend highly enough.

I initially spoke to a really helpful lady who advised me of the process. I sent my instrument cluster off for my Ford Focus … More MK2 on Monday and it was returned on Wednesday. I was really impressed with the speed and professionalism of the service. I would certainly recommend to anyone else and can’t thank you for enough for the speedy works carried out. Thank you!

TLDR; - I've saved many hundreds of pounds by trusting this service.
In full; I needed a BCM clone onto donor because … More my previous one was corroded, but partially functional. I chose to trust this service based on previous reviews so I hope this is enough to convince another person to put their expensive electric item into their care.
I posted my BCM to them and they notified me that it had arrived with them (Phew!). It stayed with them for about 4 business days before they notified me that it was then out for delivery the following day.
Plugged the BCM back into the car and I am happy to report that this has indeed remedied my electrical issues and saved me a lot of money!
I'd use the company again absolutely!

Sufficed to say they fixed everything . Absolutely chuffed.Great job guys!

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 … More off the left headlight. The 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 took my FRM3 module to ECU connection to be repaired as I was having faults with certain lights on my E91. I was working … More away for the week so I dropped 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.

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

I actually can't believe how effective the repair to my Ford Focus MK2 cluster has been, I was trying to delay my review … More to see if the faults would 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 👍

Very very pleased so far with the service despite two replacement ECU not working in my van. I was kept informed from the … More outset and my replacement ECU's 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

My Daughter's 09 Focus showed all the classic faults of a bad instrument cluster. 'Engine Malfunction' warning, … More 'Speed Limited' 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 !
