Diagnosed P0335 for free on non-starting Panda - fixed next day :)
Mobile service, friendly, knowledgeable and sympathetic to older cars being run on a budget
Previous garage charged 20EUR to scan OBDII for codes, found nothing and diagnosed faulty ECU.
Michael O'Sullivan came out, diagnosed for free, ordered the crankshaft position sensor cheaper than I could have got it, fitted next day and cleared all old codes. Very happy
