Volvo V70 2.5TDI won't started after sitting for a few hours
 

Hi I'm a new member.

A few months ago I bought a Volvo V70 2.5tdi as my 1st car, it ran great and all. Took it to the shop to change oil and all filters, after changing everything the car ran great, but then after 1 week the car stopped starting, it took me 3 tries to start the car.

I put the key in, turn it to 2, wait like 10 sec and then start turning the car on.... White smoke starts to come out of the exhaust, and I keep giving it gas to start, after 2nd try it usually starts if I give it alot of gas.

Temperature is good after starting, if I turn the car off, it will start healthy after.

(I'm driving like this for 1 month already, my right leg is strong. lol)


ps. sorry for the bad english, im all the way from lithuania.

Hello there , difficult to start Tdi engine is usually due to injection pump timing being incorrect . When they do start , you get a lot of white smoke until the engine warms up ( quite a long time ! )

Another reason may be glow plugs not working & making starting hard work .

You really need someone with Vida & Dice to read any error codes & check the dynamic timing of the pump ( you do this with engine running @ 80C )

Sorry it is all in English I cannot type in Lithuanian

Good luck & best wishes for a quick result

Thanks man! No need to type in Lithuanian, I understand English perfectly.

Sounds as though fuel is leaking back to the tank hence the continuous cranking to bring the fuel to the injector pump.

What year is your TDI? Early TDI's (MSA 15.7) have copper crush washers on top of the fuel filter housing which, if not correctly tightened or the mating surface is damaged, can let air into the delivery line. Ideally they should be changed with the filter. The later 2.5D (MSA 15.8) has a white plastic diesel preheater valve on top of the housing which can get disturbed/damaged on removal and refitting of the fuel filter.

Hi

I had similar issues with my 850. You might want to think about whether a cambelt is needed. These are due every 80k miles, and may well be why the last owner sold the car. It is a challenging job and relatively expensive compared to the value of the car. Stretch / wear in the belts can change the timing, giving the symptoms you describe.

Here is my experience https://youtu.be/VeCP63Z3ggY, but it started off with being slightly troublesome to start over winter. New glow plugs made no difference.

Hey, all belts have been changed. I've invested so far 1,2k into the car, and I bought it for 1k. Hope it's just some filter mulfonction or something, I'll be taking it to the shop tomorrow. Will let everyone know what's wrong.

Hope it all goes well. Keep us posted.

Did the car have this problem before the belts were changed?

No, it was before the belts.

Perhaps they used the ‘cut belt in half and ease the new belt on’ technique. One of the garages I had a quote with said they would do that to avoid issues with the timing. In which case, the bad timing will be maintained. Was the job done by a Volvo specialist?
