REMEMBER TO DISCONNECT BATTERY!! Bought replacement part from ebay with correct code. For this airbag ECU it was 0K. To find your ECU number you need to read airbag ecu with VCDS. There you need to find ”Component: ” line and you will find the 4th line saying something like ”0K” and that is the part I ordered. Part number + that ”0K” and got it working. It needed vcds for clearing codes of course but no adaptation etc. Including picture to help finding the component part. Replacement for this part took aprox 1 hour - including cup of coffee at the start. Hopefully someone finds this helpful in the future.

Updating this also: Yes indeed it worked. Repair took 1hour including a cup of coffee.

Hey, I am changing one replacement part tomorrow. Bought it off ebay. You need to read the airbag ecu to know which part you want to buy. Here is picture from the superb I am fixing: As you look the ”component:—” you see that there is 0K text there. According to internetwizards (+the actual dealership in Finland) that is the component code for your crash sensor. So you need to read your ECU and see that text what it says. Hope this helps.

Thanks! Maybe I shall just buy new sensor then aswell and not even try used ones. Did you happen to order it yourself with that part number?

Sorry to open this again, but: Did this work? You just replaced this sensor with the same part number? I have the same problem but with superb. Thanks in advance! - Mikael

Wanted to bump this for other people: today when trying to get rid off issues with 01221 airbag code (another thread) solved the TRC issue which is actually straight forward with water ingress problem. Sealed the pollen filter and gave floor mat some drying. TRC light gone.

I believe its this one. Drivers side crash sensor! Image included.

For future reference: For LHD cars the sensor is locatee underneath the seat and the floor mat. You need to take seat off. Undo battery just incase! Its held on front with 2x 13mm bolts. Undo those. Then take off two screws from the back of the seat. They are under plastic caps. Take those off. Then unscrew the screws and just slide the seat off. Be careful not to use too much force because of the wiring. Pry off the plastic coverings on the doors and on top of the floor mat behind the clutch/brake. Then just lift the mat and voila, you will see sensor just under the seat.

Attached pictures of drivers side wiring.

Hey, AWT engine 2004 manual superb. I have checked front wiring (fixed now) and also rear door wiring and still getting 01221. I have vcds and it says 01221 faulty. Where might be the sensor then? I really cant find it. also under the seat yellow connector seems fine. Suggestions? I am out of them now. - Mikael

Update: Engine light off and thermostat replaced. I took out the throttlebody off first and I had nice access to thermostat housing bolts. Took around 1h 30minutes for me. Now I need to lure out the TRC issue!

Wow! This is a new one for me! I will try replacing the thermostat firstly then. Cheers for the quick answer!

Forgot to mention: going to replace thermostat and coolant sensor since gauge needle is at 0, or well bottom maybe. I have VCDS available in our garage.

Hey! I have been struggling lately with my sisters car skoda superb mk1, AWT (1.8T) 2004. (Manual) She bought it one year ago and problems started around christmas: First code p0170 and replaced lambda, problem stuck. MAF went bad -> replaced and engine light was gone. Now the engine light is back with code p0130 and p0135 and I replaced lambda again. Both times it was ready fit lambda by NTK. Engine light is gone for now. (200kms driven today) Around january/february TRC light came and I cannot remember the fault code but I replaced the unit under the backseat and the TRC light comes back every now and then. Any ideas what to fix / look for? Is there some common places that wires or water might get into that both of those ecus or something similiar? And so on to the coolant temp sensor: Is it really behind the engine and you cannot see it, but you can like.. feel it? C clip and pull? Any tips to this? I have tried to look from forums for other posts + youtube but they all keep giving octavias or audis which are similiar but not the same. cheers for advices already! - Mike
