Curiouser and curiouser said Alice (Or Alek)......Well I`ve ordered the Blue band sender anyway BUT my dealer tells me that this is for a pre 97 1.3 Felicia.

Much head scratching and poking around within the microfiche reveals the part number of my ORIGINAL sender unit 357919501.

However going on your positive experience with the WRONG sender I am going to try it too and damn the consequences.... :eek: :eek: :eek:

More on this thread:

I have just been on the phone to my local Skoda dealer, discussing TempSender issue again. He explained that over the years, the various Felicia engines had a "number" of warm start problems, and with the benefit of hindsight, most were cured by using a TempSender with a different resistance... The Blue Band version certainly fixed my car.

Hope this helps,

Well the sender should be in stock tomorrow afternoon.

With a bit of luck I`ll be able to collect and fit tomorrow evening or Fri mornin.

If this works It will prove beyond doubt the essential positive nature of the Net !

Interesting how it takes a bit of ferreting to get the news about a "Number" of warm start issues.....!

Out of idle curiosity, I took a few measurements from the 2 green band TempSenders that don't do the stuff at warm start.

I don't really want to take out my new Blue band just to measure it (and lose yet more antifreeze).

The 2 green bands (one genuine VAG made in Luxembourg, one pattern part made in Italy) both seem to be within about 10% of each other:

Done in the kitchen:

400 Ohms resistance @ 90deg C,

1300 ohms @ 15deg C,

8000 ohms @ Minus 15 deg C (in freezer).

I wonder what the Blue Band measures?

So far the reports from the front are all positive.

This VERY simple mod appears to rectify a VERY annoying problem with the 1.9D engine.

It also means that the cutting and pasting is rendered null and void.

SO at this point I would recommend Pt No. 6UO 919 501 B as the solution to this particular Hot Start issue.

All for around £20.......Plug n Play !

Park your skody on a bit of a slope, let the engine cool a little until it refuses to start. Then let it freewheel to about 10mph and jump start it in 2nd gear. If it fires straight into life, then like mine, there is likely to be nothing wrong with the electronic circuit or major mechanics, there is just not quite enough power in the battery to kick it into life. In my case, I merely uprated the battery from a 60ah to a 72ah and most importantly from 550 starting amps to 630 (Millfield Autos -Peterborough) comes with a 4yr guarantee for around

interesting. I just tried mine to see what its reading

200ohms @ 92 deg c

1044 ohms @ 16.8 degrees c

6400 ohms@ -6 degrees c

I too am also have problems with hot starting, so the temp sender was the 1st thing i changed. The van has had new glow plugs too. I have noticed that the starter motor does sound sluggesh though, I put this down to the previous owner cranking the engine over for long periods trying to get the thing to start with kaput glow plugs (all 4 old ones looked pretty sooty!) there was also a spare starter motor in the back of the truck when i bought it! I've had the battery tested and its known to be good, so im putting the prob down to the starter motor lacking the grunt to spin the engine quick enough. Even on cold start the engine sound slow to turn over, but i think with the glow plugs its just enough to get the thing to fire.

"...I have noticed that the starter motor does sound sluggesh though,..." - That suggests you need a new battery. Check it's showing over 12v across the terminals with the engine off, and if, not get a new battery before doing anything else.

well i thought that at first, so got my mate to check it with a battery tester, down at the garage he works at and he told me it was fine. gonna go check it again in a min using the old fashioned multi-meter test.

well checked my battery. It shows 12.5v with the engine off. When cranking the engine over, it drops to 10v and with the engine running it shows 14 volts

It's not the battery itself then. Try checking the starter feed cable, and the block earth are secure and conductive at both ends.

well i had a day off work today, so figured i would look into my hot start problem. as ken suggested i took a look at the starter feed cable. looked fine at the battery end, but the end that goes onto the starter was pretty corroded. so i took it off cleaned it up with some wet or dry paper and gave the thread a going over with a small wire brush. whilst i had it off i figured it wouldnt hurt to run a fresh wire too.

I've kept the original, but also made another one out of an old bit of car audio amplifier power wire as its pretty chunky. connected it in parallel with the oe item.

I've also added an extra earth cable, I've run this from the battery earth, to one of the nuts on the passenger side strut.

started her up and the motor turns over quicker, which is good. so i took the skud out for a little drive, just enough to get it warm. got home let it sit for a few mins and tried to start the engine again. the glow plug light didnt light up, but hey presto the engine fired straight away!

so basically i think the bad connection was all the problem was. Seems to run better with the extra earth wire fitted too.

It's the perfect solution, the elettric connection, from battery to start engine are lacked from factory, I advise to make this work to fix the hot start problem.
