Steve and the team at A1 BMW were incredibly helpful and understanding when I had a big problem with my BMW 535D. They kept me informed throughout the whole process with feedback via email and phone, and, unusually for a garage, documented pictures of the repair process step by step and gave me great advice afterwards. They never pressured me into having work done that I did not wish to be carried out, and made me feel extremely welcome. I will certainly use them again in the future. 5 Stars.

Came here for walnut blasting and plugs/coils. Location is close to Stevenage train station (10-15m walk). The team are very friendly and knowledgeable. Price is competitive, and they are fully transparent, sending you photos and videos as they do the work, etc. Will be coming back for all BMW work.

Honestly can’t rate these guys highly enough, quality work. Such an amazing and knowledgeable team, always willing to help and really go the extra mile. Will always use these guys with my BMWs.

This was the first time using A1, and I was a bit nervous, having suffered bad experiences elsewhere. It was convenient as I live locally, so I dropped the car off and walked home. I was messaged when the work was completed, and I walked back and picked the car up.
I found the customer interface was friendly and well organised. I liked how I could arrive nice and early and park the car safely with reduced risk of getting the paintwork scratched. I received useful reports as the job progressed.
I had ordered an oil change service, and I decided at the last minute to get my air-con looked at. This late decision caused no problems for them, and both jobs went well. The job was cheaper and much better than the VW dealer who failed with the air-con. A1 were much more polite than the main dealer, whose service manager was incredibly brusque. It was a good decision to ditch them and go with A1.

Very knowledgeable and friendly technicians will explain all the work being carried out in detail and give you a good understanding of what is being done. Fair pricing for specialist work. I will be coming back.

I have a BMW 5 Series 530 2017 3.0 Diesel. Work I had carried out included inlet manifold replacement, walnut blasting and cleaning of the cylinder head intake ports due to carbon build-up, new brake discs and pads for the front, new battery, and tyre pressure sensors for all 4 wheels. I was provided with pre-work and post-work pictures, and updates during the work. Communications from Steve were great, and everything was carried out in a timely and efficient manner. I am very happy with the work. Will I use their services again - I think so!

Steve at the front of house was brilliantly helpful and really knows his stuff. I don't trust many repair shops with my BMW M2 (this was my 1st visit to A1), but they did a great job replacing a cracked rear spring and a damaged undertray. It's now booked in next week for a full DCT gearbox service.

My BMW 118D F20 broke down and had a drivetrain issue. Rang these guys up straight away and spoke to Steve. I brought the car in the next morning to them which they then done a full diagnostics and found an issue with the EGR and inlet manifold. They ordered the parts and fixed the problem the following day. Car now runs beautifully. Will recommend to others with German cars they know their stuff and are very knowledgeable. Brilliant work guys thanks.
