TCV boost pressure solenoid

[IainG]

Hi
Mine was a Denso one, both times, from this local company.
The numbers do seem to cross match though.
I didn't pay the £170 on the website though, I paid £138 which doesn't seem too bad

Thanks Iain.

Is there a specific method or tool for moving this type of belt tensioner, to allow me to again swap out the alternator See eBay link below.

The auto parts people will swap it for a Bosch btw

Sorry no idea, I just used the alternator to pivot back into position to tension the belt. Others might know. Think Haines say something about it. Also if you have VIDA there will be a description there about routine and tools for changing the alternator. Also I am sure in VIDA there is an alternator test procedure, that tests it is working correctly at different battery temperatures.
Just double check your fault codes again just to see if that code is from something else and or see if it will reset before changing the alternator again.just in case the lowvoltage had caused the code to be generated by another module and the code is not self clearing??

I think it needs a software patch according to this guy. Read this before. See 3.48 minutes in.

the tool is a large torx socket used in the centre of the tensioner its shown in the aux belt change video on youtube .

The software patch is just to let the cars ecus know whether you have a 120A or 150A alternator, as long as you're replacing like for like you don't need any software changes.

If you've got VIDA you can read what type of alternator the car is configured for in the vehicle configuration list (Diagnostics -> Details tabs).

Possible alternator types are...
Alternator 120A PWM
Alternator 150A PWM
Alternator 150A MFR
Alternator 150A LIN, Bosch
Alternator 150A LIN, Denso

The 4 cylinder engines are usually PWM types, and you just need to match the current rating of the alternator.

The 5 cylinders are LIN types, and it's important to get the right manufacturer. Be aware that when buying a reconditioned LIN alternator you really have to match part numbers and not just the branding on the box, as you can buy a reconditioned Denso alternator from Bosch!

Hi Simmy.
I will get back to the original topic eventually btw, but this tensioner is not the one that requires the torx socket unfortunately. Just got a Haynes manual, that shows the exact type, and it requires the tensioner centre bolt to be turned anti clockwise, then a drill bit to be inserted into a hole on the top to hold it out of tension as such. I'm going to post a pic of the Haynes photo shortly, to help others

there are several types the torx one being most common some use a 17 mm bolt head and or if air con is fitted the pin to hold off the tension is common i usually use a small Allen key to hold i was unsure of which type you have so suggested the most common there are different types dependant on year type or model just to keep us on our toes its even more difficult when you work on others Peugeot Citroen vw ect ford they all have similarities. has the new alternator solved your voltage problems?

This first replacement (Lucas 150amp) is charging the battery, but the car is still showing the engine power system urgent message.Dont have Vida so gonna call Volvo dealership next week, as I'm loath to swap it out again.

So as promised, and hopefully to help others before I get back to the original turbo issue fix, heres the Haynes method for lowering the non-torx belt tensioner on a 2009 2.0L diesel S40 - for fitting a new alternator that is:
