Beetle tdi remap

5
James did an excellent job on my beetle tdi, I got a stage 1 remap and it’s totally transformed my car. It pulls like a train and is also a lot better on fuel now. Someone recommended him to me, I’m recommending him to anyone. He knows his stuff ⭐️ ⭐️⭐️⭐️⭐️⭐️

Blown up VW engine and they worked magic to get it working.

5
I highly recommend JS Auto. The guys are genuinely amazing. I had no idea what I needed doing and I’d heard some horror stories about VW engines builders and parts on VW forums , but after a chat with these friendly guys they instantly put my mind at rest with a rough price and plan.( which was bang on ) they were helpful and advised with the whole rebuild and parts I needed and didn’t need. They even tested parts I’d bought else were to make sure they up to the spec I needed. The knowledge they have about VW engines is amazing and they was only a text away with help when needed. Honestly if you need work doing on a VW car or air cooled engine these guys have got what you need. 5⭐️ service

Vw Transporter T4 work completed “5 Star”

5
I recommend this garage to everyone who is looking for quality work at a the right price. James carries replaced my Vw T4 timing belt, water pump, tuned the engine/turbo, replaced the 5th gear to increase economy, replaced gearbox oil. All the work was absolutely spot on. 5 star service 👍🏻
