BMW's straight-sixes are a big part of why Fuengirola owners go looking for a BMW mechanic who does more than oil changes. An M140i, a 340i or a well-kept M3 is exactly the kind of car that rewards a good remap, and at SRM Performance in La Línea we see BMWs every day, from high-mileage 118ds to M4s on custom exhausts.
The B58 in the M140i, M240i, 340i and M340i takes a stage 1 beautifully, and a healthy N55 is still a very willing base. On older N54 cars we check the high-pressure fuel pump, wastegates and injectors before asking for more. On the F80 M3 and F82 M4, the S55 crank hub is the subject every owner has read about, and it's worth knowing where your car stands before you add power.
Diesels have their own well-known story. The N47 in the 320d and 520d has its timing chain at the back of the engine, against the gearbox, so if it starts to rattle the fix is a big job that's best done early. Oil leaks from the filter housing gasket and rocker cover are classic on older BMWs too, and they tend to show up as a burning smell after a run up the motorway.
From Fuengirola we're just over 100 km away, so most people make the trip for something worthwhile: a map, an exhaust, the timing chain, or several jobs at once. We're an independent garage, not a BMW dealer.

Frequently asked questions
Do you remap BMWs with the ZF eight-speed auto?
Yes, it's very common on B58 and N55 cars. We'll explain the gearbox options for your specific car once we've seen it.
My F80 M3 is one of the cars people talk about with the crank hub. What do you do?
First we check the car and explain the risk based on how you use it and the power you're after. If it's needed, we do the S55 crank hub fix.
Do you do the N47 timing chain on a 320d?
Yes. It's a long job because the chain sits at the back of the engine. You'll get a fixed quote before we start.
Are you a BMW main dealer?
No. We're an independent garage that works on all makes and sees a lot of BMWs.
