Well, it's EGR time again! I bought the van nearly 5 years ago at ~99000 miles. I'm sure I saw a receipt for a new EGR' in the paperwork but I can't find it now. Either way, the date of manufacture of the old (aftermarket) EGR is 2018 and the van (Euro 5, 140) was registered in January 2016...

If a double like is possible this one deserves it. Needs to be copied and pasted into every EGR / charge cooler leaking discussion. In industrial heat exchangers there are flexible packings and in some cases sliding mounts that deal with thermal expansion, the auto world design engineers don’t...

...Seems to be running OK but a bit of rough idling I guess (but nothing major). I rang the code check and got back p0401 - insufficient air flow EGR. So I guess the EGR is blocked or the value is faulty? Hefty quote for the mechanic. Wondering if I need to bother to replace the EGR or I can...

I took it for an MOT. Passed without any issues. Still got the engine light on the dash. Apparently the EGR and Air Mass Flow are reading ok so there’s nothing serious. I’m told that it might be that the EGR needs cleaning or replacing. If it’s coming out to get cleaned I’ll go with replacing...

Just a warning, the VW dealer MOT examiner failed me as my egr was blanked off. I'm pretty bloody certain no other MOT tester in the country would though. Why would they even look at the egr pipework? I had to replace the small pipe which I'd luckily kept and do the old coke can blanking mod...

Your EGR insufficient flow fault requires either an 'EGR flush' or replacement, depending on who you use for repair (Flush is usually a dealer repair, as most independents don't have the correct tooling) The P046C00 fault can be ignored.

Had the egr cooler ever been replaced? Thats where I would start.

...leaks and stains with the trusty brake cleaner to find the sources, I have ran into another issue.... I noticed one of the bolts behind the EGR pipe(?) was soaked in oil. I thought right away that the joint might have split at the flange and it's leaked onto the bottom bolt. I went to take...

Just had mine done £685 at an indi - van feels so much better - probably not VW part but as almost a disposable happy.

Hi, I'm about to do a preventative EGR strip out and clean at 45k miles on my 2019 CXEC bi-turbo. Trying to obtain correct pipes before I start as these will be replaced whilst I'm at it. I understood the rear pipe was upgraded to a cast design with part number 04L131521BH. However the VW bot as...

I'mpretty sure that my cooler is blanked off. In case the old egr wasn't closing properly even when coded out.

Hi, Has any one had any experience of the following Good or bad please Thanks in advance

Hole on the manifold? Getting exhaust gases back from the EGR circuit? Got any pics or vid clips?

I know your pain!! My diagnosed EGR failure turned out to be a leaking coolant pump. VW jump straight to EGR failure for coolant loss - feels like a good money spinner.

There is mention of a new EGR in the first post but chances are it may not be a genuine unit.

Interesting. Not an expert, but would you try to explain the science behind your thesis of EGR helping to produce better torque at lows? More intake pressure (while warmer and with less oxygen)? Or is it another internet myth?

The current price of diesel is probably the best way of preventing EGR, DPF and charge cooler from clogging up. 🥸

Hi all Had my egr blanked and mapped out for the obvious reasons, im away on the first trip and I have noticed that the van is using massive amounts of adblue ie started with 5000 miles range, I have covered 700 miles and it is down to 2000 miles range so at this rate it is going to be using...

Get another Pierburg egr cooler. they are cheaper. A common coolant leaking area for a CFCA is the coolant flange

That’s a clean one, other than the coolant leak you got your moneys worth. At least on that type of EGR you can buy a new gasket.
