RE: Fault Codes E70 4.0D

[swally76]

Morning All,

My 40d is throwing up the following codes
P0031-H20S BANK 1 SENSOR 1
P0034- TURBOCHARGER BYPASS VALVE CONTROL CIRCUIT LOW
P0101- MASS/VOLUME AIRFLOW "A" CIRCUIT RANGE PERFORMANCE
P0245- TURBOCHARGER WASTEGATE SOLENOID "A" LOW
P245c- EGR COOLER BYPASS CONTROL CIRCUIT LOW
Could these codes be linked to one issue or would I have to troubleshoot the codes individually ??
Also does anybody have any schematics/photos of where the parts associated with these codes are located within the engine bay ??
Any Help would be great guys, Also from my previous post regarding High Pitched Whining whilst accelerating it was a loose air intake into the air filter box - Once it was reconnected the noise has gone, Happy Days

Thanks in advance for your time,

Paul

I'd suggest the codes are related.
Taking a wild stab,
I'd say one of the intake pipes / intercooler  is cracked and or you have intake leaks.
Depending on mileage inlet manifold gumming can be an assumption to.
Though relatively easy to pull the inlet system apart, it would be my first checks, on the soundness of all pipework.

Obviously with little information it's extremely hard to assess

Realoem.com will show you inlet schematics in component parts..

Totally appreciate the info mate, I was going to take a look at the MAF Sensor first!! I'll have a look at realism.com & then give it a shot from there.
I'll post & let you know how I get on, thanks again
