Turbocharger solenoid valve

[Richard Braun]

We’re in the east of England needing to get back to Ireland. We possibly have a faulty turbocharger solenoid valve. Flashing coil came on. Called AA who cleared flashing and said might be faulty valve. Any views on it being safe to drive?

The error code that the AA found was P22D100

The error code that the AA found was P22D100

What Does the Engine Code P22D1 Mean?​

Character "P" in the first position of Diagnostic Trouble Code (DTC) represents the powertrain system (engine and transmission), "2" in the second position means that this is a ISO/SAE controlled OBD-II (OBD2) DTC. "2" in the third character position in a DTC indicates that the fuel and air metering and auxiliary emission controls is experiencing a malfunction. The last two characters "D1" is DTC number. OBD2 Diagnostic Trouble Code P22D1 means that Turbocharger Turbine Inlet Valve Control Circuit High has been detected.

How Serious Is the Code P22D1?​

For now, this issue is not serious. Carly recommends you to check this issue on a regular basis and check if it gets worse later on.

If this is the N75 or 'Moo valve' the common indication of an (upcoming) problem is a moo sound coming from behind the dashboard/engine bulkhead when you turn the engine off.
I had the sound (also similar to the soft close on the side door) on mine and last week changed the valve for a new one (£45 for branded new one and about half hour to fit). Although I had the sound there had been no change in performance or error lights.


Valve is in the centre of the photo with the 3 pipes coming off it. Already unbolted from the carrier plate. Carrier plate is attached via 3 10mm nuts.


Back In position and tightening up the bolt on the bulkhead. All the bolts are 10mm but I needed different length extensions or different 10mm spanners for each one.

My engine is the single turbo 140bhp. Believe (but don't know) that the BiTurbo engines have 2 valves.

This was the report carried out today

We’ve managed to get the van back to Ireland. Whereabouts is the solenoid valve located?

Top of the engine bay, mounted in the middle under the windscreen wipers. Easiest bit to spot is the 1” round black filter.

The end of the tale (hopefully). Got Van back to Ireland driving in stages of up to 130 miles. Went in and out of limp mode. After considering options we took the van to the VW Van dealer In Kilkenny and sent them the diagnostics report we’d had. They had it in for a week and gave us courtesy car. They said they tried various things and fault kept reoccurring. In the end they replaced a Converter. Van needed new ABS sensor as well so got that done too. All in about £420 so not as bad as feared. Went out last weekend and all appeared ok
Also discovered that our AA Ireland membership covers us for Rescue Plus which includes recovery back to chosen garage and alternative temporary vehicle if we’d broken down.
Thanks for advice and input.

Just for info

The 204 has 3 valves in the centre of the engine bay at the top, look similar to windscreen washer pumps. One for EGR and other two for the Turbos.

Worth having VW All In Warranty, Service and Breakdown 2 year package if available.

Warranty scheme isn’t available in Ireland and in any event van is 2015 so would be outside the scheme if it were.

Judging by your bill you don't have the wallet raiding hourly rate to factor in. £135/hr last quote that I had.
