Engine Management light

I'd have thought your garage could/should have been able to tell you why the air bag/SRS light was on when he plugged his diagnostic box of electrickery in while investigating the EML 🤷‍♂️ Very unlikely that the 2 are related. SRS problems can be down to damaged wiring under the driver's seat due to frequently being moved back & forward.

Re the throttle body .... sometimes you have to bite the bullet & go to the dealer despite the cost. 😓

What engine does your motorhome have. Following the VAG emissions scandal my npw sold Skoda Yeti had the "fix". A while later the engine management light came on. The local Skoda garage in Norwich near where we were pitched said it was safe to drive and saw it next day. The diagnostics recorded a "Faulty throttle position sensor". They cleared the log and all was fine. It did not require a new part.

Sometimes you need a main dealer with the manufacturer's diagnostic gear. Others may read the codes but not be able to clear them.

Many thanks for your replies, on Monday I will give the dealer a call.  Would the Skoda dealer be Simpsons?  That was where I bought the motorhome from  5 years ago and it was a brilliant buy.

I don't believe it was them. The dealership was actually in the town centre.

Is it a Fiat Ducato? If so, this may be a common issue. We had it happen to us and ended up having to have a new ECU fitted by a Fiat dealer. It was pretty expensive and we were a bit miffed to find this is quite common but possibly easy to prevent. We found out that it was probably caused by starting the engine when the battery (the engine battery) is low. It happened to us after one of the lockdowns, when we had our motorhome in storage and weren't allowed to travel to check on it or maintain it. I do recall checking battery levels before starting the engine and the engine battery was low... about 84%, I think. I can't remember the voltage. The leisure battery was fine, as we have a solar panel. I mentioned the low battery to my husband but he was able to start the engine, so we just carried on. I can't remember the details, but this may have happened more than once, before the warning lights started. We had a faint warning light at first, that we weren't that worried about. Then the airbag light came on, along with an alarm, beeping... and we were grounded. Had to cancel a trip, as we were told not to travel with that issue, but to get it sorted pronto. Apparently, sometimes, just resetting the ECU will fix it. That is cheap. In our case, that didn't work. Lesson learned... we now make sure we start the engine regularly and keep the battery topped up.  Hope you get yours sorted and if it's the same issue as us, hope this helps you to avoid it again in future.

Many thanks, I can see similarities with my situation.  By coincidence I had my habitation service done on Friday and the engineer said 6 weeks ago he had exactly the same happen to his Ducato.  He checked the Earth connections and it cleared and has not come back.

I always remove my batteries over winter and keep them charged at home, so flat battery should not be issue.

It really is a minefield.

Thanks for taking time to enlighten me.
