Driving home today in my 1999 Golf Mk 4 I heard a scraping sound whenever I went over a speed bump. Looking under the front of the car I can see the big black plastic sump guard / under tray (not sure what they're technically called) is hanging down just an inch off the ground. It looks like its ripped all around the edges and very little is holding it on.
Should I get this replaced or is it really needed on a 10 year old 150,000 mile car? If its just keeping the engine bay cleanish then I reckon I can do without.
Thanks for any advice...

A car that age and mileage, Winter coming, nasty wet cold weather, I would have thought the car would appreciate all the protection it can get try and repair the one you have.

I had a similar problem on a Daihatsu Fourtrak that i had and i refixed it by taking the sump guard/cover off, putting great big washers on the retaining bolts and refixing it that way as the washers covered the corrosion on the sump guard and held it in place with no further problems
It would probably be fine without but you'll always be concious its not there and wondering why was it put there in the first place??
Might be worth attempting a refix before discarding it or even looking for a secondhand one on ebay or internet scrapyard searches

Need to do same for my motor. Garage said just buy one off ebay and they'd fit it. £20-£30 and job's a goodun.

Stand by for the bad news-the middle section on my Passat TDi estate cost me £126 and that was with fitting it myslef (its dead easy all you need is the mounting bolts and a screwdriver). If you can get one of ebay good luck to you.
If you dont replace it you will notice a reduction im mpg (about 2-3 mpg) and road noise is increased and you will end up with a filthy engine bay and when traversing floods the water will fill up into the bay quicker and towards your cold air pick up for the engine.
Make sure that when you drive through puddles you do so slowly as half the time this is what rips them off (along with driving on rough fire road at Kirroughtree).
Looking under the front of the car I can see the big black plastic sump guard / under tray (not sure what they're technically called)
Technically called a "shit shield" but it does affect the drawn of air throught the rad, winter time you'll be good for temp but very bad for collecting "shit" and water+salt and lots more "shit".
If you have no ramps or a pit, park half on a big kerb and put a sheet or big bit of cardboard down and see whats gone on, if its just replacing bolts then source them from a motor factors or just drill and cable tie it back together.
If its smashed then source a no genuine replacement and fit it yourself, they are a piece of cake/piss.
Hope this helps mate.

Thanks to everyone for their suggestions.
I got it to a garage today who lifted it on a ramp and from underneath it was obvious that a few inches worth of the tray had been ripped off to the rear but there was still plenty hanging on protecting the engine compartment from water spray so they just ziptied it back up securely - and no charge, which is always nice.

Was looking for information on a damaged sump and found this site!
Anyway, any help would be appreciated. I have driven my golf 1998 for nine years without problem, regardless of flying over humps. In the last 6 weeks (after having my shocks replaced and a slow oil leak repaired), whilst going over humps (slowly), I heard a bang on one occasion and a scratching sound on the other. Result? I have now cracked two sumps (oil completely leaked out in about 2 minutes!!). Luckily my husband was with me both times otherwise he would not have believed that I was going slowly. I had learnt my lesson following the oil leak and my mechanic had asked me to drive slowly. Now that this is second time the sump has cracked I do not believe it is related to my 'problem driving' but either the shocks or something that protected the sump is no longer present. My mechanic said he would put something plastic over the sump and having found this thread. I'm now assuming it is the guard. Does anyone please have any advice as I am really reluctant to pay for 'repairs' that will not necessarily solve the problem leaving me lacking confidence in the reliability of my care.
I look forward to any suggestions, advice etc and will next visit with a cycle query. Oh maybe not, as mine was stolen last year

If your sump is bottoming out you have major problems. The only part of my car that has bottomed out is the very bottom of the gearbox as its the lowest point on the engine. I would suggest that your suspension that was replaced may have been replaced incorrectly or worse still the wrong parts and potentially your front suspension strut springs may have broken (Its not uncommen after a harsh winter and is very common on Fords). Easiest way to check is look at a similar car to your model with no dropped suspension or wide wheels etc and see how large the gap is between the front wheels and top of the wheel arch. They should be similar. If they are not its indicative of broken springs (may have been tired too start off with before they were compressed by the mechanics doing the shock absorber repairs).
Should not be massively expensive to repair.
If its not that then check your engine mounts as its the only other thing that will make the enginebe closer to the floor!
