Limp Home Issue - Codes: 01268 & 00519

[Stratos]

Hi,  first post here.
This is not my car but my Mom's mode of transport.
It is currently in limp home mode and my Mom never noticed!!
I took the car up for an MOT and noticed it no longer has any go in it.
After the car was MOT'd, I asked the guy if he could read any codes from the ECU as there is no engine light.  He said he could and gave me two codes which were:  01268  &  00519
They kind of relate to the MAP sensor but after a quick look - cannot find it?
Can someone tell me where to find it and if anyone else has had this issue, please point me in the right direction if it's not the MAP sensor.

The car is a 1999 Seat Alhambra TDi 90 (or 110)??

The 268 code relates to n146 qauntity adjuster in fuel pump.

The 00159 is for map sensor.

I would concentrate on the map first though,it will be located in the boost pipe somewhere between turbo and inlet manifold.  A multi plug with 3 or 4 wires going to it and connected by 2 screws. If you find and replace it make sure you go with genuine vw or a Bosch one as after market ones are useless.

The Mk1 Map sensor is found inside the engine ECU which is located inside the car behind instrument cluster, there is a small tube from the air charge pipe that goes through the bulkhead to the ECU.
There is a small length of tube inside the ECU that can split which will give the effect of no boost.
There was a write up about this on another site.

Oh yes school boy error on my behalf I have even posted in a thread about it previously
And if I remember correctly it is located behind the dash and requires instrument cluster removal?
