Hi Guys if anyone has a noise on cold start up that's sounds similar to a failing water pump but disappears after 10 seconds it could be the auxilary belt tensioner as I just replaced my belt and tensioner yesterday and what a difference. £70 fix so not too expensive just thought I would give everyone a wee heads up and the best way to confirm this is remove the auxilary belt and do a cold start and see if the noise has disappeared as well as feel for play in the pulleys as well.

I have an astra 2.0 cdti 2012 and when the car is cold the gears are hard to select and feel stiff until the car is warm. Then everything is fine!!

Think my temp is a little bit out [Image: https://uploads.tapatalk-cdn.com/2018022...f422d1.jpg]

Hi all,

Bought a new (for me) 2014 GTC in Feb and love it!

However, I've noticed that on cold the engine ticks for around 15-30 seconds on cold, then dies down but can still be faintly heard. When cold it's so loud I can hear it from inside the cabin with all the windows shut.

I've got a 2-year warranty so have taken it back and Vauxhall told me that it's normal for the model? I've spoken to an independent mechanic and he's convinced it's tappits even though I've been told they're hydra

Hi, I've just bought my first diesel and it happens to be a GTC SRI 2 ltr CDTi. I love it. My only question so far is that when I initially start the engine from cold, it's not a smooth idle and you can feel it through the car with a slight rocking. Is this normal? A common problem? After a few minutes, it idles fine and there seems to be no other issues. I searched for the answer before posting so apologies if the answer is buried here somewhere.

Thanks.

Hi, I have an astra j 2013 1.7 cdti 110 hp A17DTE and as soon as the weather has cooled it shows me that the DPF is full and to continue driving. What could be the reasons why the car makes so many regenerations if for example today I drove 1000 km on the highway and everything was ok and tomorrow morning when I start the car I get a warning with DPF on board. Any opinion is highly appreciated.

Hi guys I have a Astra 2.0 cdti 14 plate and recently it has started making a lot of noise when completely cold on startup but only then. After it’s been started it doesn’t do it at all. I’ve had cam belt don’t and water pump done when I bought the car 6months. Not sure if it’s chain or belt on these and if the tensioner could be at fault or possibly dual mass maybe ?? Any ideas thanks

Hi, I’m new to the forum, never really had to ask for help as everything’s on here but I have a problem I can’t find an answer to. I have a 2010 2.0D Astra J that won’t start when it’s cold. Initially I thought it was the battery and have replaced that. I then changed the glow relay and plugs and I’m still having trouble when it’s cold. It will start with easy start (I know I shouldn’t use it in a diesel) but after using that it will continue starting all day until the engine gets cold again. I
