Leon cupra tdi 150 fault codes!

Hi Guys,

Hoping at least one boffin can help me

have recently had an mot which it passed with flying colours.
The next day, a whole host of problems decided to baffle me

ECU light
T/C light
Coil light

went to have a diagnostics reading this morning and the following codes were discovered

17068 glow plug ecu
16706 Engine Rpm Sensor
17957 Boost Control Valve / wastegate
17849 EGR Valve
17552 Air flow meter

is it likely that all of these faults exist as im likely to be scrapping the car if they do lol

17068 glow plug ecu- I keep getting this fault, while it is here could any1 tell me where it is located? please

Cheers man, spent ages trying to get info of where it is

as i say im STILL learning to translate vag language lol. physical wiring loom?
the car itself is in limp mode, brake lights are still working though. no boost leaks as have checked all possibilities of this.

17056

fixed the problem now guys
replaced glow plugs and connectors and everything seems to be spot on now.
thanks for the guidance
