Re: N75 valve on 2.2 DW12 2.2 HDi engine

Re: N75 valve on 2.2 DW12 2.2 HDi engine

Indeed, this engine has the most torque of all the engines used in the 406 - 314 N⋅m (232 lb⋅ft) / 2000rpm.

Re: N75 valve on 2.2 DW12 2.2 HDi engine

Hi Not sure if the EGR is blanked - will get that checked. Garage think it could be a wastegate issue on the turbo but I mentioned there's no wastegate on that one (2.2 DW12 - ECU controlled turbo) They thought car was to old for that (non wastegate turbo) but the 2.2hdi was one of the latest engine...

Re: N75 valve on 2.2 DW12 2.2 HDi engine

Hi Garage think the turbo may be at fault, so having it removed for an inspection. Even tried fitting a new Swirl Flap EV. Car drove OK for a short while at speed after new Swirl Flap install then it flat spotted again. It was mentioned to me a couple of years ago that the engine note was indicative...

Re: N75 valve on 2.2 DW12 2.2 HDi engine

Hi

Not local but will ask them to try that.

Is the swirl solenoid part number 1628.CH?

Found the thread below from a few years ago about the DW12 Vac system.

Re: N75 valve on 2.2 DW12 2.2 HDi engine

Hi

Now getting a boost solenoid fitted - is that one of those that is on the bulkhead? This is a different part to the electrovalve 1628.LQ just fitted.

Thanks

Re: N75 valve on 2.2 DW12 2.2 HDi engine

Hi

Connections checked to new electrovalve (1628LQ) and OK. Still getting the flat spots on acceleration.

Could a faulty unit be causing this? I wasn't getting this happening with the old one fitted.

Thanks

Re: N75 valve on 2.2 DW12 2.2 HDi engine

Hi I got the 1628LQ Airbox electrovalve fitted and now I'm getting a new issue that I didn't get with the old one (the previous one had one of the two small plastic pipes broken, and was causing (I think) limp mode at over 50mph constant. With the new part fitted, I'm getting some sort of 'turbo lag...

Re: N75 valve on 2.2 DW12 2.2 HDi engine

Thanks, the issue with the valve was identified when I was getting the coolant temperature sensor changed. Basically on occasion, I lose acceleration / power (limp mode) at about 55mph plus. It will then come back to normal when at lower speeds. Issue also happens occasionally when turbo wants to co...

Re: N75 valve on 2.2 DW12 2.2 HDi engine

Thanks, can't seem to locate a replacement 1628CH part at the moment...

Do you know where the part 1628LQ is located on the engine?

A pic of 1628CH located near the bottom of the page on a French Peugeot forum:

Re: N75 valve on 2.2 DW12 2.2 HDi engine

Hi. The 3 solenoids on the bulkhead are all the same part number - 1628 HC - but the ECU uses them in different ways. My T4 has an N75 valve, but it's boost controlled, not vacuum :cheesy: Hi The part I'm after is under the airbox, some sort of a valve looks a bit similar to the 1628 HC. Possibly t...

Re: Glowplugs (HDi)

I had a set of Bosch Duraterm glowplugs (Bosch part no. GLP013 0250202032) and got them fitted when the coolant temperature sensor was being fitted. Thought I would get them fitted given we are coming into winter. The glowplug light now goes out almost instantly and no more hesitant starts and 'bag ...
