Hi Guys,

Engine on my 116i was sounding a little rough lately and so I booked it in for a service for today. Yesterday on my way to work in the morning the yellow check engine light came up in traffic. I pulled in and restarted the car and it turned off. Car driving fine all the time, just sounded rough on start up for a while. Drove home yesterday and just when I got to my house my brakes went really hard on me. Seemed to lose the power assistance on the brakes. If I rev the engine brakes come back but as revs tick down it loses power and the pedal goes really hard again. Hearing a slight tick from the engine. It was overdue a service but I've always kept it topped with Castrol Edge and the electronic oil check was at max yesterday when I ran it. So the question is, what could the issue be? Seems like a vacuum related problem. Does this sound like a timing chain issue to anyone? If so the chain hasn't snapped yet or anything. what am I looking at in terms of work?

So for anyone interested. Brought the car to Colm Quinn in Galway. Was told on Tuesday that the timing chain is fine but the fuel pressure sensor is gone and needs to be replaced. Very relieved at that point. Asked about the breaks and they had no idea. Was concerned with that. Was told to pick it up Wednesday evening. Got no call Wed, rang Thurs arranged callback which never came. Same today. Eventually got a call from a manager at closing time saying it's making a strange noise when cold. They don't know what it is, engine needs to be stripped down to diagnose it costing around 500 quid and no guarantee they will find anything. FML.

Cheers for the reply man. Ya I thought it was very strange that they didn't address the issue with the brakes, seemed pretty likely that there was some vacuum issue. Not really sure what my options are around Galway outside of main dealer.

Ok Sound, I'll try get it off them in the morning. Have to decide whether to pick it up or leave it with them for further diags.

No luck with the codes. Was told they weren't available and nobody there from the service dept today. Need to wait until Monday to find out what the story is. Fuel pressure sensor was changed anyway but no update on the brakes at all.

I'd politely suggest that you bring it elsewhere.
When they bring a problem car in they run ISTA/D which gives all codes from all modules.
They can save them or print them...
If they haven't then I'd be slightly suspicious.

So I picked up the car. They inspected camshafts, rockers, vanos all seem ok. Timing was checked and that's fine too. They swapped out the vacuum pump and no issue seen there. The initial diagnosis showed a bad high fuel rail pressure sensor so that was replaced. Car got an oil service and filters while it was in as well.

The thing is they didn't detect any issue with the brakes and there is an engine noise from cold that they don't understand. They suggested that maybe the bad fuel sensor caused the loss of vacuum to the brakes? It's a strange one. They say there is a rough noise when the engine is cold and they don't understand where it is coming from. They say I would need to take out the head to diagnose and they don't know whether it is an issue or not.

Get it out of there and get to a competent BMW specialist.

Assuming you're South Galway/Clare area, take your pick of Matt in M&S Autos, Clarinbridge, Tom in Fahy's, Oranmore or even Roches Garage, Gort.

All well versed in BMW's.
