Thanks for the comments guys. To be honest, I'm pretty unbothered about the engine oil leak, it's easy to buy a bit more oil and a hell of a lot cheaper unless it's raining oil out of the bottom! Looking at the tray under the engine there was a bit of gearbox oil on the tray but no sign of...

Hi, While getting the car MOT'd and it's HPFP fixed, the dealer pointed out an oil leak under the car. This seemed very reminiscent of last year where under warranty the dealer fixed the seal between the gearbox and engine, so I asked them to have a look, and they diagnosed it as the DCT...

To close this one off, I called BMW UK complaints and they said that although there was no extended warranty on that part in the UK, they were 'aware of other customers' having similar issues' and I should contact my dealer and ask if BMW UK would 'assist' with the cost of the HPFP. I did this...

So, I eventually took it into a BMW dealer to have diagnostics done. Their notes say: All in, they've quoted me £929.24 :sick2: - doing a bit of research online, it seems as though BMW US have put a 10 year warranty on this part because of the high failure rate, is anyone aware of anything...

I've done a quick check over and there isn't any obvious signs of disconnected hoses. The airfilter is fairly new so clean (well cleaner now since I took it out and cleaned out the bugs that had collected in the airbox). M.

I've also tried using v-power, and apart from having a lighter wallet sadly my MPG still sucks at 26MPG. I'm tempted to replace one or both MAP sensors as I can't believe both O2 sensors would fail at once, unless anyone would be kind enough to offer some guidance on other diagnostics I could do...

I have a similar issue, also with a 35i, but my service wasn't recent. I've also had the engine light on with P0171 & P0174 running lean codes. These codes were cleared and they've not come back, but I'm still only getting 26MPG where I used to get >30. I've read up that it could be a vacuum...

I've had the car 18 months, and the dealer that I bought from isn't near where I live (and wasn't who I used to fix it), so I'm a bit stuck there. I'll continue my charm offensive with Allianz, my complaints lady is very efficient and attentive so you never know. Meanwhile.. How could I have...

Actually these links are exactly what I wanted, thanks very much! The fact that section is called 'Z4 E89 Z4 35i VACUM CONTROL-ENGINE-TURBO CHARGER' means I'm going to argue it is part of the turbo, and then I'll slowly wear them down with polite persistence... and then cancel the policy once...

My argument is the pressure converter is a part of the turbo/intercooler, and the fault that was detected was a turbo over boost. Am I on thin ice with this argument? I'm trying to find a diagram or pic which shows where one of these pressure converters is to see if that helps my case. There is...

Hex Nuts 4 x £0.66 = £2.38 (ex.VAT) Pressure Converters 2 x £78.35 = 141.03 (ex.VAT) Diagnosis = £74.33 (ex.VAT) Fitting and Tests = £70.80 (ex.VAT) Net total = £312.14 Total inc VAT = £374.57 M.

Hi, I've just had a claim rejected by BMW insurred warranty (Allianz). I have named component cover, which includes this: Turbocharger: Factory fitted turbocharger, intercooler and wastegate. I've described the fault here http://www.z4-forum.com/forum/viewtopic.php?f=45&t=87475, which was...

Hi, I've recently had an issue with my 35i E89 Z4 which has now since been fixed by a garage, but it seems a simple fix so thought I'd describe it here. Symptoms: Engine warning light came on under high throttle, engine put into safe mode, but is cleared by turning the engine on and off again...

Thanks so much, that's been confusing me for ages! :headbang:

I'm sorry if this is a stupid question but I've researched this thoroughly and I cant find an answer! A couple of weeks ago after my wife drove the car the 8 iDrive presets seemed to be showing a second set which were mostly empty. I've not been able to find how to bring that 2nd set back, and...
