TWG Motorsport in Peterborough

We took my wife's BMW X3 into TWG as the engine maintenance light had come on. Four visits and almost £2000 later, they still hadn't sorted the problem. But they had replaced air filter, glow plugs and various other things. We took it elsewhere, another BMW specialist, who not only diagnosed the problem over the phone - manifold needed changing and engine de-coking. When we picked up the car they showed us the clogged up manifold that needed changing - the worst they reckon they'd ever seen, and stated that any mechanic worth their salt would have seen this when they changed the glow plugs!
I would advise that you treat TWG with caution, we have no evidence that they know what they're doing and it cost us £2000!
