I've got a skoda superb 2014 2.0 CR that's going into limp mode with P0238 and P0113 errors. I've replaced air filter and both the MAP and MAF sensors but it still goes into limp mode. If you're driving and flick the ignition off and on again, you can drive normally, but if you brake/stop accelerating the car goes back into limp mode. Has anyone had a similar issue ? 

 

Many thanks,

Arran

I had a similar P0238 problem. Turns out one of the wires was cut off. Sounds like in your case, the connection is intermittent, but as soon as you brake or hard accelerate, the connection is broken and the error is shown. 

Since you've replaced the MAP and MAF sensors, I think it is quite likely that you have a severed wire problem.

Thank you for getting back to me, where did the wire break for you ? I don't have a ramp so trying to access the wires from the top has been difficult.

Your post Didn't load properly, but now I can see you explained in detail where the break was. I'll take a look underneath the car at the weekend. Thanks

Hi Arrran, I've got the exact same issue as you by the sounds of it. (Superb 3t5 mk2 2014 2.0 TDI 140hp CR DPF) Only intermittent and happens on deceleration or pulling away from a stand still from my experience. Fine on motorway (after turning on and off to get the car out of limp mode) just managed to nurse it back home. Did you find it to be a wiring issue to the sensor? I.e. wire making contact/losing contact again when the car is moving? Would appreciate your reply. Thanks 

Hi. Found the issue for this on my car. It's a broken earth wire on the intermediate connector (centre front of engine bay underneath the airbox). Had to take airbox off and the connector is pretty much bang in the middle of the radiator fans (above starter motor) Wire rubbed through and when pulling the loom&connector up the wire broke free. Suspect this will be similar to your issue Aaaran. Hope you sort it soon. Just need to put a connector on and will be out of the woods. See photo for ref.

Thanks so much for the info, I'll take a look tomorrow. I'll let you know how it goes 

No worries mate. Really was a head scratcher. Even sought expertise from a VW specialist who thought the loom went straight from the connector at the MAP sensor end to the ECU but there is definitely a half way connector as pictured. Wrapped in the hard plastic ribbed shroud which is bad for the wiring from what I hear. Let us know how you get on and best of luck!

I can't seem to find it, here's what I'm looking at 😂

Hi mate. Mine was under this hose here, cable tied onto the hose underneath. The hose is about 1" diameter. Put your hands in and should be able to feel the 4 pin connector 

I think I can see it, but its very far in, I'm going to get some scissors to remove all the cable ties

May be slightly different position to mine then. My connector wires&shroud were zip tied to the cable shroud (larger diameter) stuff I've pointed to in the image. Position of my 4 pin connector was 90 degrees to the picture I sent so it was pretty central to the two radiator fans but right at the front of everything 

Thanks for all the info! I'll see what I can do. My cars got quite a patchy history so might have been moved at some point to fix something else. 

Found it !! Heres some pics for anyone that finds this post in the future. Thank so much for the help mate
