P0238 Turbo boost pressure sensor high input
Posted: Fri Aug 02, 2024 9:10 am
Hello guys,
I have a VW Scirroco 1.4 tsi 160hp, 2009.
A while back (about 2 years ago) I had the issue where I got the fault code " P0238, Turbocharger (TC) boost pressure sensor A/supercharger (SC) boost pressure sensor A - high input.
I brought my car to a local garage where they first changed one of the boost sensors, didn't fix the issue so they had to replace another boost pressure sensor. They told me there were multiple sensors (2 or 3?, cant remember what number they said).
After they changed the second one the issue was fixed. (but costed me 500 euros..)
Last week the same issue came up again the P0238 code after a bit of driving, (also noticing it hesitates above 2000 rpm). Looked under the hood, and I found two boost pressure sensors myself (see picture in attachments): position 1 and 2 shown in provided image.
I ordered a bosch MAP sensor (cause I seen on the oem which contained a vw logo, that there was also a Bosch logo on it), and I first replaced it with position 1, erased code, still not working properly. I then changed sensor position 2 with the sensor that came out of position 1. Erased code, and went for a drive. Still not working properly.
Is there possibly a third sensor MAP that I might have missed? Or could it be that the Bosch MAP sensor (30 euros) is not recommended and should I buy an oem instead (100 euros) and try that on position 1 and 2?
Kind regards,
Vince
