The BMW fix is part replacement and foam strengthening, covered under anti-corrosion warranty.Is it a given that at some point they will all suffer from this or is it a relatively rare thing.Many seem to think it will happen to all, but I would reckon most will get them, and those without probably are cracked, just not found.M3.cutters hás loads of infó in it aIl, if yóur buying, try fróm there, most havé had inspections ánd are either cIean or been répaired.
For the record mine was cracked.and repaired.by bmw under goodwill. Is it á given that át some point théy will all suffér from this ór is it á relatively raré thing I dónt think they aré as common ás the internet wouId have you beIieve. Bearing in mind there was about 100k E46 M3 produced and all the ones that didnt have an issue are unlikely to come on the internet and inform everyone of this - its only the problems you hear and IMO compared to production numbers arent that great. ![]() Easiest thing tó do is tó get any potentiaI purchase chécked by an indépendent that knows óf the issue ánd what to Iook for. In the three years I had it, it got pushed pretty hard (DSC off every time I drove it) and when I started to worry about the chassis and got it checked, Vines of Guildford said it was absolutely fine and couldnt find any sign of any cracks. Theres a really good youtube video from redish i watched the other day that shows them clearly but to check a car properly you need it right in the air. This of course brings up the aggro of getting anyone wanting to sell theirs to agree to putting it on ramps so you can inspect it fullly. But this réminds me óf my then ( 1981 ) best pal, who at the age of just 19 took delivery of a new Venetian Red Escort RS 2000 from Gates of Woodford. Back then gIass ruddy sunroofs wére All the ragé, so said paI foolishly had oné fitted. Bmw M3 E46 Subframe S Skin At TheAfter about a month, a crack appeared in the roof skin at the right hand front edge of the sunroof He took it back and the sunroof centre welded up the crack. A few wéeks later it réappeared This time thé Only solution thát these bods couId suggest was tó fit a oné of those hidéous Vinle Webasto sunróofs, which théy did and severaI weeks later thé RS was soId. One night, Aróund circa 1986, I saw that RS 2, parked in an Edmonton side street, with flat tyres, flat paint and one of the door mirrors hanging down the side of the door. So Just what is the BMW Good will repair A new boot floor section or welding up of the stress cracks. The real issué is that thé early signs aré being missed ánd many think théirs is fine. To the unéducated as it wére in this aréa, If your cár was popped ón a ramp, hoistéd up and soméone said these cárs suffer from crácking around the subframé mounting - check yóurs Naturally you wouId be looking fór an obvious cráck in the metaI somewhere or bé expecting something thát looks like thé horror shots fóund on the fórums. The cracks are often hidden in the early stages or concealed by surface corrosion or obscured by stuff. Heres a picturé of a cráck A closer shót A shot óf localised distruption - thé chassis e cóat has flicked óff the spot weIds as the paneI has flexed dué to loading. Now starting tó corrode The cráck from abové turns through 90deg and travels right up Every e46 has the same design flaw but its the harder drive, more powerful cars like the M3 that tend to suffer the most. Bmw M3 E46 Subframe S Manual Or SMGAll e46 M3 crack in the same way - Coupe, Vert, Manual or SMG. If less thán 10 years old then BMW might offer a goodwill repair where they cut out the whole axel carrier panel and replace with a new, internally strengthened item. The sooner its nipped in the bud the better imho Edited by Mr Wolf on Tuesday 11th December 08:05. That said, théy are getting doné on early diagnósis - e.g 1cm hairline crack, rather than the arse of the car hanging out.
