Visiting on behalf of a friend with a problem with his 1999 BMW 318iS. He was travelling to the Touring Cars at Knockhill yesterday and experienced an odd loss of power with the car.
When he first described it to me he said it would accelerate fine in any gear up to 4k rpm and then the power would just die. He also mentioned a slightly raspy sound which he reckons is a small hole in his exhaust. When he got back home last night he phoned to tell me that it hadn't gone away and on the way up a hill on the motorway, he got to the bottom at 70mph and the top at 15mph. If he depresses the accelerator more than a third of the way down, it just chugs but it's fine apart from that - just sounds a little raspy.
Any ideas?? It has been suggested that it might be fuel pump related or something to do with seals in the engine. Neither of which sounded convincing to me. Its booked in on Friday to the dealer, but he would like a wee bit of good news if there is any!
