First class service, ignition switch picked up by DHL, contact by one of the girls with the quote, I then spoke to the engineer and he explained the common faults associated with this model. Unit was returned as promised and I refitted it. The unit now working as it should, and I realise that it’s had faults since I purchased it, key always a bit hesitant to turn, but now it functions perfectly. Will definitely use Autotronics in the future should the need arise. I did read a lot of reviews but decided to ignore and run with the positive ones. Great job well done to all involved at Autotronics.

Just had my Mercedes ML ignition switch unit repaired, no problems very professional, unit picked up by DHL and two days later I had update e mails and a phone call to give me the quote. I also spoke to the technician who was working on it, I sanctioned the repair and it was back to me in three days. Fitted it back into my vehicle and it’s perfect, now I know this problem I had has been there for a long time and gradually getting worse, I say this as it’s now perfect, no hesitation to turn etc. Well done and I take things at face value this was my experience and it was faultless don’t always write people off because of reviews, I gave them the opportunity and they done what they said they would
Cheers Kev

While job was not straight forward and a number of problems were encountered the support given by Autotronics was first class and problems were resolved. Work was executed quickly with good feedback when parts were with them for repair. Would use again if I required complex electronic problem resolved. Resolution for me was more satisfactory and much cheaper than what was proposed by Mercedes Main Dealer.

Nothing but praise for Autotronics ; they fixed my MB C250td EIS and Key Fob that Mercedes were unable to provide. This means that a non -starting car is now usable again. Quite expensive but no firms in my area can fix these parts so I will definitely use them again ! Very helpful staff on the phone and very quick turnaround. Keep up the good work!
