Normally at this time of year I get 44-46 mpg, 50-51 in the summer. It's a bit of an obsession of mine.

When i pointed out the broken crankshaft breather pipe to the garage, there was a fair bit of fresh oil around that area. I wonder if its made its way down to the sensor and contaminated that? That could be the issue with the o2 as you pointed at on my last question. Cheers mate :-)

Yep, that's what it says. Even goes higher if I drive economically. Obviously somethings wrong. Got an ongoing prob with EML. Codes are all pointing to o2 bank 1 ( P0135, P2243) 3 garages have said it could be the wiring or the ECU as I've had the o2 changed twice now (in case the first was faulty) Anyone else had this mpg problem and know if it's the wiring or ECU? It's getting to a point where I can't throw anymore cash at it. Fabia 1.2 tsi 105bhp 2011. 115000 miles. Maybe it's time to get a new motor. In the last month I've had, new wiper mechanism and motor, breather valve, air filter, spark plugs and leads, 3 new tyres and tracking, as well as the o2 sensor :-( The chain was done at about 85,000 miles btw.

I've got a Fabia 1.2 tsi (105bhp) se plus 2011, and was wondering why, through internet serches, some o2 sensors have 4 wires and some 5 wires? Which one should my car have? I've got an ongoing EML light issue going on. Codes on my (basic) reader are P0135 and P2243. Local garage has been working on it, so not sure how many the original one had, but the new one has 5 wires. Just trying to do a bit of research myself (as i assume we all do :-) ) Any knowledge gratefully recieved, cheers.
