Barastian so does the cleaning cycle kick in at any time? how long could it go on for?

just got my dooper back today and they cant find a fault, they took it on a 150 mile extensive test drive and guess what, the problem didnt show up....

just noticed my vanity mirror lights are not working on either driver or passenger side. everything else works so wondering if they are on a seperate fuse and where would i find the fuse box to change it? cheers

Mostly every several 100 miles. The cylce itself moslty lasts for a few miles only (5-10 mls.). I noticed when start/stop kicks in during a cycle sometimes the cylce has stopped after restart.

Didn't show up or they don't know what to do? Maybe it's our driving style? I noticed if you have a heavier foot the problem is much less likely to occur.

Haven't looked for the fuse box yet. It is probably somewhere behind a removable panel below the steering wheel/near the drivers feet. Although I'm not sure if it is the opposite side for right hand side models.

It never ceases to amaze me how dealers/ technicians are completely at a loss with things like this, they've supposedly come across the problem before but can't fix it? how??? Some specialist!!?? Can they not look up how they fixed it in the past?

Just because the ECU isn't showing a fault they cannot diagnose it even thought it is there!!

My car developed a "new" fault- in 6th gear with foot flat to floor @ arround 1500rpm the car/engine starts to violently vibrate/ missfire. If I keep my foot down it does clear and also clears if you lift off the throttle a bit.

I'm wandering if it is over fueling and once the turbo has reached full boost it clears?? One thing is normally with overfueling there would be smoke out the exhaust but there is none??

Not sure if this "new" fault is related or not but it does happen @ the same sort of rpm?

Oh also forgot to say;-

The cooling fan also comes on on my car when the cleaning cycle is on. It is normally REALLY load!! Much noisier than when the fan is on to cool the engine or to cool the Air con condenser.

My car normally goes into the clean cycle every 1000miles or so.

Full throttle (with the overboost activated) at a shade over tick-over might be pushing your luck a bit IMHO.

And, did you try the 'Italian Tune' I suggested earlier in this thread?

[markslater]

I think I know what you mean but it is not that the revs are too low in 6th. The engine starts to pull and then @ aprox 1500rpm it starts to vibrate/ misfire and after 2000rpm it pulls like a train again.

Not done the "Italian Tune" as the car is regularly drive very hard and it won't think it will be choked up.

[Barastian]

To keep you informed...

a full software update has been performed a week ago. Although there are some changes noticable (engine runs a bit smoother, radio has now a regional setting ), the hesitate problem is still there

[markslater]

Update,

Just noticed on my car the air inlet pipe from the MAF sensor to the turbo inlet had come off the turbo.

On further inspection the orangy/red seal that sits inside the plastic pipe has split.

Away to order a new seal to see if that improves things.

Wondering if you could help I'm new to forums but my seal has also split and it's my second one now in less than a year not sure why?? I had to pay £80 for the pipe that connects to turbo just to get the seal from BMW

How much have you paid for the seal and where have you got it from thanks

[markslater]

I have just found out the same, seal not available seperatly from MINI.



However as this engine is the same as the 1.6 TDCI (110bhp version) fitted to various Fords, Peugoets & Citroens the seal should be the same.

There is a guy on ebay selling an orange seal for a 1.6 HDI Citroen.

Search for citreon 1.6 orange turbo seal and it should come up, about a tenner if i remeber correctly.

Hi obviously new to this forum.
The name gives it away.
I have a Peugeot 307 1.6 HDi with exactly the same problems.

I have tried a couple of garages but to no avail.
Did any of you chaps get anywhere with it ?

I take it thats the Peugeot part number, thanks for letting everyone one know at least we now have the name of the part that may be causing all the problems.

Has anyone with a Mini had there problem cured yet?
