Hi guy's I need your input, I'm getting constant limp mode in my Leon Cupra 1.8T, more details about the car and it's specification can be found in my readers ride thread (click my signature)
This all happened after I removed the n249 valve, which I've successfully done, put in a 330ohm 10w resistor as required
I had various fault codes:
17524 - SORTED WITH NEW 02 SENSOR
17511 - SORTED WITH NEW 02 SENSOR
17608 - SORTED WITH RESISTOR
Still:
17705
Still
0.4 Bar of MAX boost
So far I have checked and replaced:
1. Brand new Bosch MAF, which hasn't done much
2. Brand new Bosch 02 Sensor Pre-Cat, which has got rid of the 02 sensor faults above
3. Checked all hoses in and around turbo for boost leaks, replaced a few of them just for the sake of it to either uprated silicon ones or ultra high quality oil lines
4. Repaired ONE massively split boost hose under the inlet manifold which was causing a poor IDLE, now fixed, there might be another boost leak under here somewhere but not big enough to cause 0.4 bar of max boost.
5. Replace Forge 007p with the standard DV, this hasn't changed anything either, dumps normal like the Forge one, so I've put the Forge 007p back on
6. Fitted New N75 E Valve, hasn't done anything
Things I'm going to do next to cure / fix this
1. Ordered a brand new genuine n75 F valve (Possibly E) - DONE
2. Ordered VAG COM HEX+CAN to do a throttle body reset, log blocks etc should be with me sometime next week - GOT IT
Now I only have one fault code:
17705 - I know this is common as much but I've always had this
It's driving me bonkers!
QUICK CAR SPEC:
Forge 007p,
n249 Removal fitted resistor,
TIP,
FMIC,
A'pexi Filter,
3" CAI,
3" Turbo Downpipe,
2.5" De-Cat,
Milltek Non-Res System,
Boost Gauge
Generic Stage 1 Map
Shell V Power Fuel
