Lack of power... Turbo problem maybe? - Moh - 22-09-2015

Haven't drove my hdi in a couple of months. Had the timing belt and full service done on it yesterday as I'm planning on driving it regularly again. I've realised that the car hasn't got the pull in it that it used to anymore.

It's really obvious that the power isn't the same as it used to be when pulling onto carriage ways from slip roads or over taking, feels a lot like a non turbo now.

Is this likely to be a split pipe or something else? I can't hear the turbo whistling either. Other than this car is sweet as a nut, not smoking and it's ticking over fine.

Any ideas?

Just over 120k on the clock if that's of any help

Uplug the MAF mate, give it a spin. If its better, then its that Wink

Its a common thing you're describing, if it is the MAF (plug on air filter box) it'll run a bit smokey unplugged, but replacing it would get rid of that and make the mpg a bit better too Wink

Timing out after the belt change?

RE: Lack of power... Turbo problem maybe? - highwayman306 - 22-09-2015

£60+ for a genuine one, thats the better option as they last a bit longer. If you have a standard air filter, you're alright, if you have a cone/oil(K&N) filter...sack it off and go back to standard Wink

Ah, true. I was assuming the timing was done by an experienced mechanic...but some suck ass!

but the overtaking issue sounds MAF too Confused

The gentleman who done the work is actual and old mechanic with a very good reputation. If its not the MAF ill ask him to check the timing. Cheers bud

Done this today mate and it's defiantly pulling a lot better with it off. don't suppose you know anywhere I could buy a genuine one from? A lot of the eBay ones seem to be copy parts.

Glad i could help ThumbsUp

I think it's Siemens that's the OEM part, don't hold me to that but sometimes the scrap yard can be a good place for a replacement Wink

I got mine for £15 and it works...for how long I don't know though, but its alright for the interim Wink

euro car parts might do them too, but they can be pricey Wink

sorry I can't help further, someone may be along with some more knowledge ThumbsUp

RE: Lack of power... Turbo problem maybe? - MY95 - 23-09-2015

Have a look on Eurocarcare buddy, got one for £50 posted a few months ago, genuine siemens too!

RE: Lack of power... Turbo problem maybe? - Poodle - 23-09-2015

You can get genuine siemens for £80ish, very worth it imo.
